III IIIIIIIIIIIIIIII RECEIVED OCT 1 3 1998 DIV. OF MINERALS October O8, 1998 Mr. Jim Dillie Division of Minerals and Geology 1313 Sherman Street, Room 215 Denver, Colorado 80203 Subject: Battle Mountain Resources, Inc. DMG Permit No. M-88-112 Quarterly, Monthly and Bi-weekly Sampling Dear Mr. Dillie: All required sampling was completed during the month of September. Enclosed are analytical reports from Accu-Lobs and Sangre De Cristo Lab (SDC) for the recent bi-weekly, monthly, and quarterly sampling periods as specified in the April 1992 Abatement Plan. Humidity cell test results from CORE lab is also enclosed. The cross-reference Table between sample identification numbers, sample types and sample locations is also attached. Analysis That have not been received will be forwarded to you as I receive them. Field and rinse blanks were collected as part of the QAlQC. All surface water stations were inspected and RS-4 and RS-6 were found to be dry. Staff gages were maintained at RS-3, RS-4 and RS-6. The maintenance involved adjusting the gage to compensate for a change in the level of the stream bed and the installation of new sample bottles. The work was completed by Mr. Peter Barkmann of Halepaska and associates. Vacuum on the lysimeters was verified and no water was present to sample. When we checked the piezometers on the main embankment of the tailings impoundment on 09/30198, the piezometers were dry or contained well below 12 inches of water. The two new west pit piezometers were measured for depth to water on 09)29198, with the following result: BF-Twos 12.35 ft and BF-2 was 16.10 ft. The other piezometers in the West Mine area were also checked with the following result: PW-1 was 14.45 ft, PW-2 was 15.50 ft, PW-3 was 23.60 ft and PW-4 was 26.30 ft. The underdrain was at approximately 28 gpm. For the month of September the leak detection flow was approximately 33 GPAD. We continue to keep the collection pond al a low level to minimize leakage.
